    Roads and Highways

    Canada's first highways were the rivers and lakes used by Indigenous peoples, travelling by canoe in summer and following the frozen waterways in winter. (See also Birchbark Canoe; Dugout Canoe.) The water network was so practical that explorers, settlers and soldiers followed the example of the Indigenous peoples. (See also Coureurs des bois; Voyageurs.) To a greater extent than most other countries, Canada depends for its social, economic and political life on efficient communication and transportation. (See also Economy; Politics.)

    Robotics in Canada

    Robotics is the branch of engineering that concerns robots: reprogrammable, multifunction manipulators designed to move objects and complete tasks through a variety of programmed motions. The field includes the conception, design, manufacture and operation of such machines. Robotics overlaps with a variety of other electronic and engineering disciplines including artificial intelligence (AI), bioengineering, computer science, mechatronics (the engineering of both electrical and mechanical systems) and nanotechnology. In the late 20th century, Canada distinguished itself in the field with the development of the Canadarm for space missions. Despite the challenges of competing in the international market, Canadian companies, institutes and researchers are now world leaders in the development of AI applications for robotics.
